Noctilucent clouds are a weather phenomenon unique to summer months at latitudes between 50 and 70 degrees north and south of the equator. Inhabiting the mesosphere at altitudes of 75-86 kilometers, science regards noctilucent as highest clouds in Earth’s atmosphere. Too faint to be seen in daylight, there’s good reason why they’re known as luminous or night shining clouds. Noctilucent clouds can only be illuminated by sunlight below the horizon at astronomical twilight when lower levels of the atmosphere are in Earth’s shadow.

For immediate noctilucent gratification, ponder noctilucent perfection by Adrien Mauduit of Night Lights Films –
On April 5 NASA scientists launched sounding rocket mission AZURE (Auroral Zone Upwelling Rocket Experiment) from Norway’s Andoya Space Center. Twin rockets deployed chemical tracers capable of allowing researchers to track the flow of neutral and charged particles during an active geomagnetic storm. Emergency service switchboards were inundated with UFO sighting hysteria – seems no one bothered to alert residents of AZURE’s chemical meddling.
Lights over Lapland webcam operator Chad Blakely captured the first chemical puffs. Video below from Adrien Mauduit documents the spectacle.
Take a moment to ponder timelapse perfection by Lucie Debelkova – https://www.youtube.com/channel/UClDKSZTXcuOz4lC_Zv183Ng Lucie travelled along ancient trade routes from the Atlas mountains, across the Sahara to Marrakech during darkest Moon phases to capture night skies without light pollution. Dark skies reveal the Milky Way of our ancestors – mesmerizing, irrefutable and bristling with thought provoking imagination.
